Argghh.... got my car thinking I was going to do all maintainance a month ago, and due to time / place to do it I see myself paying to get my car serviced

I got an oil change coming up in about 500 miles, just did the 82K mile service last month.

I don't have my service book with me here in the office. I had planned on changing the rear end fluid and the tranny fluid at the 92K major service interval, but am entertaining just doing it now at 85,339 miles I am at now?

thoughts? If I do it now how much should I expect to pay at an independant shop? an hour for tranny fluid change and an hour for rear end sounds more than enough time for me, no? so and hour plus filter / fluids? or would they charge less than an hour?
HOw much in $$ do you guys pay for this stuff?

Oh, and do it now or wait to 92K...?
